This may sound sad, but honestly, I just can't for the life of me think of a compliment that has stuck with me. Well, to echo [MENTION=9232]megm87[/MENTION], I do find great satisfaction when someone compliments me on a design or something I've done in that required a creative aptitude. Though, there's a huge catch to this too, if I personally feel like the thing being complimented on just plain sucks, then the compliment will roll completely off my shoulders. If I'm proud of something I've worked on through and I feel it's some divine intervention, being just a tad dramatic here, and someone compliments me on that, then yes, THAT will feel really good.
To answer the OP intent of this thread, I suppose it's a compliment having to do with ability and a certain skill. Something that not just anyone can do. Complimenting me on being nice or helping them here and there, I really don't need to hear it. It doesn't pain me to be nice haha. It's like complementing me on being me, being alive. Like so what?
